The invention relates to a device (17) for the quality control of solid pharmaceutical products such as tablets, comprising a testing means (9) having a sensor for checking one or more parameters of the products. The device (17) consists of a housing (2) and a test chamber (15) that is arranged above said housing (2) and that is formed by a floor (4) and by a protective hood (1) that is placed onto this floor, whereby testing means (9) are located in said chamber. Drives (14) and, if applicable, supply means for the testing means and the transporting means (5, 6, 7) that are arranged in the test chamber (15) are located in the separate housing (2) encapsulated so as to be at least splash-proof and dust-tight vis-à-vis the test chamber (15) and the environment. At least parts of the feed lines (11) leading to the drives and the supply lines that provide energy to the testing means inside the housing (2) pass to the outside of the sealed test chamber (15) in an encapsulated manner so as to likewise be splash-proof and dust-tight.
